I think there's a conflict in what "self driving car" means.

I think many users imagine being chauffered around while they read a tablet, potentially not even needing a drivers license.

Meanwhile I think realists and Elon Musk expect a car that is doing most of the menial parts of driving while a licensed human driver is still hands on but not doing much work.

We're close to that realist scenario in many ways for some areas - though I'm sure we'll see a spike in tragedies once it first goes out and people attempt to treat it like scenario one.

Scenario one is a very long ways away from being universal.
